This takes a little effort but it can be done with a volt meter. Typically they measure this with the repair computers in the dealerships and such. For a single wire sensor trace the wire color back into the cars computer. The computer is usually under a seat, passenger side dash or under the console. To make sure you traced the right wire disconnect the o2 sensor and using the connector end (of the wiring harness NOT the o2 sensor)use your meter and "ohm out" the wire ie check connectivity. On the computer side the harness connector will hopefully be the typical molex connectors that you can press your probe into from the outside. (Do not disconnect from the computer it wont start!).
Now that you know which wire into the computer comes from the o2 sensor, reconnect the o2 sensor and warm up your car. You may consider leaving the voltmeter probe in the molex connector before starting if you are concerned about poking around after it is running. In the volts setting (0-2 or 0-5 volts) leave the positive lead in the connector and the negetive lead to ground (usually anything metal connected to the frame). When you first start your car your numbers will be low 0.1-0.3 volts as this is a rich mixture necessary until the car warms up. Once warm expect numbers in the mid to high range. meaning 0.5 to 0.8 volts. If you bounce the throttle you will see a cyclic response from low to high 0.3 then 0.8 or so as the engine emits its exhaust. Consult your specific auto manual for acceptable ranges.
It is usually between 0 an 1 volt with 0 = rich and 1 equal to lean. Your auto manual should give you outputs for idle, and possibly under load (driving at a constant rpm)
If you have a multi wire sensor the same applies but you have to fish out the "signal" wire coming from the sensor. The other wires are typically for heating the sensor.
... I have done it myself on several cars but I don't know what they all look like and behave like so use this only as one data point.
The only fix is to replace it. If you are mechanicly inclined, this is a doable deal. Before you replace the sensor you should check the wiring for resistance you can use a volt/ohms meter (vom) and test the continuity of the wiring to the sensor.
You can "test " the sensor using a DVOM ( digital volt ohm meter) if you have a manual that has the spec, also helps to have an inferred temperature gun to confirm the temp at the sensor.
You will have a no spark situation. Testing it with a volt meter is easy. Twist the crank shaft slowly by hand and watch volt meter. If there is voltage and no voltage the sensor is good. No readings sensor is bad
A volt meter will do the job.
Use a volt meter.
you can ck the speed sensor with a volt meter while you have someone spinning the wheel. make sure your volt meter reads mv`s
Volt meter should be in a 5 volt scale.
Continuity tester, volt meter, clamp on amp meter, megger and ohm meter.
With an AC voltage meter.
test light or volt meter
could be a sensor or relay
Fluke is a very good and very popular test meter.
To check a cam sensor you can either use a scanner which plugs into the vehicle communication port or use a volt meter and check if the sensor produces a pulse like reading on the meter.
You will need a volt meter to adjust the sensor and a lab scope to determine if you have a glitch in the sensor.
A simple test with a volt meter will give you the answer.
Set your multimeter on the 20 Volt DC scale.
240 watts to 120 volts? Or 240v to 120v? What kind of meter? As in an electrical test meter?
Test Prod Scale meter Zero corrector Zero Ohms adjust Scale selector
you need to test with ohm. meter... there are resitance test. and could also be output test using a volt meter. you will need a service manuel to get sepect.....for the corrct make ,model, and year,,,,... what is your problem that your having.....
voltage meter.set to DC voltsBuy a cheap volt meter.
Another name for a volt ohm meter is a multi meter. VOM
Noise levels of sound in the air are tested by a sound pressure level meter (SPL meter).Noise levels in an electronic circuit are tested by a volt meter.
With a volt meter or a test light ,it also might be a fuse
There are several different things you can do to test it. If your RX runs rough and you suspect the mass, you can unplug it while it's running and see if it runs better with it unplugged. If it does, replace it. You can also tap on the sensor with the vehicle running. If tapping on it makes the engine stumble then replace it. If you have an ohm meter you can check the Resistance across the sensor, but you would have to find out what the acceptable range is for the sensor. You can also take a volt meter to the output lead of the sensor. With the vehicle running and the volt meter on the out put lead you should get a steady voltage output at idle. As you increase throttle the voltage should increase with it. It should increase smoothly and with no "dead" spots. If it doesn't do this or you have a dead spot, replace it. Of course a "live" read from a scan tool would be ideal but most car owners don't have one. Good luck!
